- They're adding a new easiest setting in the difficulty selection which starts players with full item/magic stock, a dragon shield, and the ability to open chests without keys. The game also retains all the arcade difficulty settings and there's a super hardcore setting for pro players.

- There's New Game+ function now. Instead of getting a Game Over after completing the game, players can use their characters to start new games while retaining their levels and stats. You can also choose higher difficulty levels in these subsequent playthroughs.

- Stages you have completed can be replayed with a chapter select option, where you can pick which part of the stage you want to start from. There are also boss strategy videos to help players who have problems beating the bosses.

- Bonus content includes tons of artwork and original design materials from the development of the arcade games, introduction videos for the various classes, and video interviews with the original developers of the arcade games.

Looking at the UI for the bonus features... I'm really starting to think M2 might be doing this port... that would be... amazing.

I played these at my local arcade back in the good ole' 90's. I bought this last week but I just finished Hotline Miami and currently playing the FFXIV Beta. I'll start it up once the next phase is over.
